Jan and Louise find an unsolved murder case in Sweden that has similarities with Natasha's, although this one has an unusual signature: the victim's ring finger was cut off. Louise doesn't believe that the murder has been committed by Anders Kjeldsen. Meanwhile, on a farm that Anders Kjeldsen stayed at as a child, the police make a gruesome discovery. Stine is forced to help Anders with the women in the basement, who are planning to escape.

Louise realises that Anders Kjeldsen does not kill alone but has a partner who is the dominant of the two. In the basement, Emma tries to persuade Stine to help her to escape.

Jan and Louise find a dress belonging to Natasha – the first victim – which Anders Kjeldsen had hidden. That same night, Anders tries to kidnap another woman. Stine Velin attends her big brother Mikkel's 40th birthday party and reveals a dark family secret.

Stine Velin is taken into police custody, but insists that she is also one of Anders Kjeldsen’s victims and does not know where either Anders or Emma are.
